Under the current rules, there may be many circumstances where one can force a draw even though one's opponent already has 24 points.
These all depend on being able to prevent them from having more than one seed on their side of the board.
They will move their single seed around their side of the board and eventually distribute it to you (it's critical to ensure that you won't have a seed in you Position/Pot 1 when this happens): when they distribute the seed to your side you distribute another to them and the game should proceed in a continuous loop until they agree to a draw.
This should be possible to do with 3, 4, 5, or 6 seeds left on the board - dependant on those seeds being on one's own side of the board and not where they will have to be distributed to the opponent before he distributes his only seed to you.
If there are more seeds still in play, it may be possible to simplify the game down to one of the aforementioned scenarios.

When the majority of players learn how to do this I believe that games ending at 24 points will become rare, as players will be aiming to score 25 points or more.
